Description

The present invention relates to a marking device for a long frame material that performs marking necessary for assembly on a long frame material such as a lower runner on a panel frame material for a steel house.

Conventionally, a wall panel frame used in a steel house has an upper runner and a lower runner as an example of a pair of long frame members arranged horizontally with a predetermined interval in the vertical direction, and the upper runner and the lower runner. And a plurality of studs arranged vertically at predetermined intervals in the horizontal direction. In order to join the stud to the upper runner and the lower runner as designed, it is necessary to mark (scribe) the upper runner and the lower runner in advance the positions where the stud is screwed. As one of the marking methods, the upper runner and lower runner made of sheet steel channel steel are faced to each other, and the runner positioning frames that can be stored with the openings facing sideways are arranged in parallel. An arrangement is known in which a scale is slidably arranged in the longitudinal direction as a finger-mounting surface on the upper surface of the runner positioning frame (see, for example, Patent Document 1).

JP 2000-336936 A (FIGS. 5 and 6)

However, the conventional marking method still has the following problems to be solved.
Since an operator looks at the construction drawing and performs marking, human error is likely to occur, which may cause an assembly failure.
Moreover, since the upper runner and the lower runner face each other and the runner positioning frame is pressed and restrained, it takes a long working time.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide a marking device for a long frame material that can reduce an artificial mistake of marking by an operator and shortens an operation time.

Since it moves along the moving direction of a conveyor, a moving means is simplified compared with the case where a long frame material is moved.

In the marking device for a long frame material according to claim 2, the marking means is fixedly arranged, the first gripping means is mounted on a carriage that moves along the transport conveyor, and the first gripping means is moved. Thus, since the pair of long frame members move on the conveyor, troubles due to the movement of the marking means can be prevented.

In the marking device for the long frame material according to claim 4, since the marking means is disposed on both sides of the paired long frame material mounted on the conveyor, a sufficient space for attaching the marking means is ensured. be able to. Furthermore, the marking means can mark the long frame material based on the CAD data of the long frame material created for design by the CAD system and the CAM data of the long frame material created for processing by the CAM system. As a result, human error by the operator is eliminated, and the work efficiency is greatly improved.

The moving means 65 is provided in the cart 43 of the marking device 10 for the long frame material, and the upper runner 11 and the lower runner 12 gripped by the first gripping means 20 are moved. However, the present invention is not limited to this. The upper runner 11 and the lower runner 12 that are gripped can be moved by driving the conveyor without providing a moving means on the carriage. Further, the carriage 43 is stopped by moving the movement amount S, and the upper runner 11 and the lower runner 12 stopped by the fixed marking means 24, 24a are marked. However, the present invention is not limited to this. When the conveying speed of the lower runner 12) is low or the marking speed by the marking means is high, the marking can be performed by the fixed marking means while moving the carriage. On the other hand, when the carriage (upper runner 11 and lower runner 12) is fast or when the marking means is slow, marking can be performed while moving the carriage and also moving the marking means. .

The marking means 24, 24a is configured to perform marking based on the CAD data 63 created by the CAD system 61 and the CAM data 64 created by the CAM system 62, but is not limited to this. It is also possible to perform marking based on other data without using CAD data and CAM data.
Further, cutting means and drilling means are provided upstream or downstream of the marking means, and short cutting and drilling can be performed while marking the upper runner and the lower runner based on CAD data and CAM data.
